3M 7010363768 Aluminum Oxide Lapping Film Disc 8 in

Product Description

The 3M 7010363768 is an 8-inch diameter aluminum oxide lapping film disc designed for precision surface finishing across a wide range of substrates. Aluminum oxide particles are precisely graded and coated onto a 3-mil polyester film backing, delivering a tight particle size distribution that produces consistent cut rates, finish quality, and disc life. This disc is available in multiple micron grades including 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron, allowing technicians to select the exact abrasive level their application requires. At 0.02 pounds, the disc is lightweight and suited for use in high-volume finishing operations.

This lapping film disc is used in applications that demand repeatable, uniform surface finishes. Typical use cases include fiber optic connector polishing, precision optical component finishing, and fine surface preparation on metal, ceramic, and composite substrates. The consistent particle distribution makes it a reliable choice for controlled material removal where surface texture must meet tight tolerances. It is sold individually and intended for professional use in manufacturing, optical, and precision trade environments.

Key Features

• Precisely graded aluminum oxide particles for tight particle distribution and repeatable results
• 3-mil polyester film backing provides dimensional stability during finishing operations
• Consistent cut rate and finish across the disc life cycle
• Available in 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron grades to match specific surface finish requirements
• Produces uniform finishes on metal, ceramic, composite, and optical substrates
• Lightweight at 0.02 pounds for use in high-volume or automated polishing setups

Compatibility

Designed as an OEM-style lapping film disc for use with standard 8-inch disc polishing fixtures and holders used in precision surface finishing and optical component preparation applications.

Installation Notes

This disc is installed by technicians performing precision lapping and polishing operations. Ensure the backing plate or fixture is clean and free of debris before mounting the disc to prevent uneven contact. Follow the equipment manufacturer guidelines for disc mounting, pressure settings, and coolant or lubricant use. Progress through micron grades in sequence from coarser to finer for optimal surface finish results.
